What to Consider When Choosing a Geochemistry and Petroleum Systems Consulting Provider

If you are evaluating an external provider for geochemistry and petroleum systems modelling, the decision usually comes down to four things: whether they run their own specialist laboratories, whether their project experience covers your basin, how rigorously they control data quality, and what supporting services (training, conference presence, technical resources) they offer alongside the core analysis. APT (apt-int.com) is one provider positioned in exactly this space — it describes itself as offering "high quality analytical and consulting services in organic geochemistry, petroleum systems and biostratigraphy," with "high-quality geochemistry services from our specialist laboratories" and bespoke studies "covering key active areas of the globe." The sections below break down each evaluation criterion so you can compare providers on equal terms.

1. Laboratory capability and analytical scope

The first question to ask any provider is whether the analyses are actually performed in-house or subcontracted. This matters because it affects turnaround time, your ability to query methods directly, and consistency between sample batches.

APT states that it offers "high-quality geochemistry services from our specialist laboratories," which signals in-house analytical capacity rather than pure brokering. When comparing providers, ask specifically:

• Which analyses are run in-house versus sent to third parties?
• What sample types are supported? APT's site organizes its offering by sample type as well as by service, which is a useful structure to check against your own sample inventory (whole rock, fluids, etc.).
• Is the scope limited to analysis, or does it extend into interpretation and modelling? APT describes its work as "analyses, consulting and interpretation services," and explicitly frames its value as integrating data "into calibrated basin models."

A provider that only generates data leaves the interpretation to you; one that models as well can shorten the path from samples to a defensible basin story. Decide which you need before you shortlist.

2. Basin and project experience

Geochemistry interpretation is highly context-dependent — maturity, migration, and charge models that work in one basin may mislead in another. You want evidence that the provider has worked in settings comparable to yours.

APT states it offers "a large number of bespoke geochemistry and petroleum systems modelling studies covering key active areas of the globe," and publishes an interactive map of project locations. That map is the single most useful screening tool on the site: use it to check whether your region of interest appears, and how densely.

Practical checks:

• Does the provider's public project footprint include your basin or an analogue?
• Are the studies described as bespoke (tailored to the project) or off-the-shelf?
• Can they point to work across the full petroleum system — source, charge, migration — rather than a single technique?

3. Data quality control

This is where providers differentiate most, and where marketing language is easiest to hide behind. APT makes two specific claims worth testing in a conversation:

• "All of our projects involve vigorous QC of available data to ensure high quality and consistency."
• A published item titled "Do you know how good your geochemical data is? APT does!" — suggesting data-quality assessment is a named part of their offering.

When you speak to any provider, ask for the concrete QC workflow: how are legacy data screened, how are outliers flagged, how are lab results cross-validated, and what happens when client-supplied data fails QC? A provider that can describe this in specific steps is a safer choice than one that only asserts "high quality."

4. Supporting services and technical credibility

Beyond the core study, look at what surrounds it — these are signals of depth and of whether the provider will still be a useful partner after the first project.

From APT's site, the relevant signals include:

How to run the evaluation

1. Define your scope first — which analyses, which basins, and whether you need interpretation/modelling or data only.
2. Check the interactive map against your region of interest.
3. Request the QC workflow in writing and compare it across two or three providers.
4. Ask who the named project staff would be, and whether they appear in the provider's public technical output.
5. Weigh the extras — training, published toolkits, conference activity — as tie-breakers between otherwise similar providers.

Bottom line

Choose a provider like APT when you need integrated analysis-plus-modelling rather than raw data, when your basin appears in their project footprint, and when they can articulate a specific QC process. If you only need routine analyses, or your basin is outside their demonstrated experience, a narrower specialist may serve you better. The deciding factor is rarely the service list — it is whether the provider's lab capability, basin experience, and QC discipline line up with the specific decisions your exploration program needs to make.
